Abstract
The endolymphatic potential was recorded from various vestibular parts of the labyrinth from which the cochlea (in the case of guinea pigs) or the cochlea, lagena, and sacculus (in the case of pigeons) had been removed. This endovestibular potential of the isolated vestibule declined during anoxia and recovered after anoxia in the same manner as the endovestibular potential of the intact labyrinth. Its non-anoxic level was the same as in the intact labyrinth; i.e., +5 to +8 mv in the pigeon and +2 to +5 mv in the guinea pig. It is, therefore, concluded that the endovestibular potential is independent of the cochlea, stria vascularis, and endocochlear potential.
